What is Chlorobis(ethylene)rhodium (I) dimer?
Chemical properties
red-brown powder
The Uses of Chlorobis(ethylene)rhodium (I) dimer
Chlorobis(ethylene)rhodium(I) dimer is used as a precursor to rhodium(I) norbornadiene catalyst, which is used in an asymmetric 1,4-addition of arylboronic acids to cyclic enones. Further, it serves as an important organic intermediate. It catalyzes the dimerization of ethylene to 1-butene. It is also used in the preparation of homogeneous catalysts.
